To all whom it may concern:

Be it known that 1, WILLIAM E. BERTRAM, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Linotype-Machines, of which the following is a specification.

The resent invention relates to improvements n linotype. machines and more especially to the mechanism for ejecting] the slugs [from the'mold after each casting operation, and the object of this invention is to provide simple and improved means for operatively connecting ejector blades of different sizes to the ejector slide whereby blades corresponding to molds of difi'erent sizes or to the different adjustments of a mold may be quickly and easily applied and removed relatively to the'ej ector slide, thereby facilitating the operation ofnintenchanging these bladesand adjusting the machine to produce slugs of difierent lengths and thicknesses.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing :-Figure l is a side elevation of an ejector slide andsan ejector blade provided with. meansembody ing the present invention for detachably connecting the slide to the difi'erent blades;-

thicknesses. In adjusting or altering the 1 machine to enable it to cast slugs of difl'erent 'sizes, it is necessary to employ an ejector blade which corresponds to the size of the mold and inpractice a set of blades of difierentsizes is provided in order that the slugs of corresponding sizes may be properly .ejected 'from the mold in which they are cast.

The present invention provides simple and improved means whereby the different ,ejector blades may be quickly and easily interchanged with respect to the ejector slide, thereby minimizing the delay incident to altering or adjusting the machine for the production of slugs of different'sizes.

The preferred embodiment of the invention is shown in the accompanying drawing, 1 designating the usual ejector which reciprocates in the mold slide and is operated as usual by a pitman one end of which is engaged in the socket, 2 of the ejector slide. The constructions of the mold slide and the means for operating the ejector siide are well known in the art and, hence, t ey That part of the ejector slide to which the difierent ejector blades are to be attached is preferably undercut to form a transverse recess or seat 3 which is'adapted to receive a correspondingly shaped part of each ejector blade. Fig. 3 shows one of the ejector blades 4 and the rear end of this blade is-formed with an extension 5 which corresponds in thickness to the depth of the seat or groove 3 of the ejector slideand such extension of the blade is adapted to enter and fit said seat or groove in such a manner that the rear face of the ejector slide and the rear face of the blade will occupy the same plane. The body of the blade 4 is of uniform thickness throughout its extent although the extensions 5 of the larger blades of, the set will be of reduced thick ness as compared with the thickness of the body ofthe' blade. It willbe understood that a set of ejector blades of appropriate sizes are intended ,to be usedbut the extensions or attaching portions 5 of thedifl'erent blades of the set will be ofthe same thickness whereby they may properly fit the seat Each of or groove 3 of the ejector slide. these blades when used operates thr'ough its corresponding mold to eject the slug therefrom, in'the well known manner.

The meansprovided by the present invention for detachablyconnecting the differentejectoriblades to the ejector slide embodies a suitable number of hooked pawls which are adapted to engage a corresponding number of appropriately shaped recesses formed in the attaching portions of the ejector blades. In the present instancea pair of pawls 6 are used, these pawls being turnable on pivots 7 secured to the ejector erative'ends of the pawls. As the ejector slide in the present instance is'provided with a pair of locking pawls, the operative portion or extension of the ejector blade is also provided with a pair of recesses or sockets which, when the-blade is in operative relation to the slide, receive the operative ends pfthe respective pawls. The recesses or sockets 10 of. the blade are formed with notches 11, these notches extending laterally and in the same direction from the recesses or sockets and these notches form locking shoulders 12. When the ejector blade is in operative relation to the slide, the locking projections 9 of the pawls engage in the notches ll of the respective recesses or sockets of the blade and such locking projections on the pawls abut againstand interlock with the respective shoulders 12. The recesses 01' sockets 10 are properly shaped to permit the pawls to rotate about their pivots toengage and disengage the locking projections 9 thereon with respect to the shoulders 12.

- The movements of the pawls to engage and disengage them with respect to the blade are in a plane parallel to the plane of the blade and although the attaching end or portion of the blade is comparatively thin, the co-' operative locking surfaces of the projections 9 of the pawls and the shoulders 12 of the blade are of suficient area to maintain a firm connection between the blade and slide,

and the necessary movements of the 'pawls to lock and unlock them with respect to the blade are provided for although the parts occupy a very compact relation.

Different means may be provided for operating the pawls to lock and unlock them with respect to the ejector blade. In the present instance the pawls are connected so as to move in unison by a bridge member 13 which is pivotally, connected to the pawls and operates in a transverse'slot 14 of the slide; An operating handle or lever 15 is provided'at the forward side of the ejector slide,

6 it being pivoted to the slide at 16 and it is conber13. The free end of this handle or lever I of an ejector slide, an ejector blade having nected by a pivot pin-1'1 to the bridge memis preferably formed with a flexible section 18 and this flexible section bears a dog '19 which-is adapted to seat in a notch 20 in the slide to retaln the pawls in locked position or to engage in a second notch 21 in the slide to retain the pawls in unlocked position, disengagement of the dog 19 from either notch being effected by springing the flexible section 18 of the handle outwardly, the resilience of said section serving to normally retain the dog in engagement with either of these notches. The handle may be readily shifted to simultaneously move the pawls into locking and unlocking positions. The ejector slide and blade are adapted .to reciprocate as usual in the mold slide, the edge 22 of the blade and the edge 23 of the ejector slide. toward which the locking projections 9 and the notches 11 are directed being in alinement and cotipera-ting with a guiding wall 24 of the mold slide while the rear faces of the ejector slide and the blade which are in the same plane coiiperate with a wall 25 of the mold slide. lhe ejector blade is therefore prevented from moving either in an edgewise direction or in a flatwise direction to disengage itself fromthe locking pawls of the ejector slide, the locking and unlocking of the ejector blade being controlled wholly by manipulation. of the locking pawls'. 1

I claim as my'inventionzf 1. In a machine of the linotype class, the combination of anejector slide, an ejector blade, said slide and blade havingabutting ends, and a pawl connected to one of said parts, extending across the abutting ends of such parts and having a hook-shaped.-
